> Directable Mirrors: A Better Way to Focus the Sun
It looks like a sound concept but it will take quite a while to get it
to market- he obviously hasn't yet built a prototype. One possible
refinement (if very high power densities are desired) is to bias the
balls in a panel to approxiamte a spherical surface, so that all the
individual beams converge at the target, instead of shining parallel.
Alternately this would allow fewer panels for a small installation yet
still reach useful tempratures to run a heat engine.
